I was lucky enough to get to try out this sauce on the day it hit stores here in St. Augustine. They rated it at a 7/10, which I think reflects the amount of heat this sauce produces to an acceptable degree. I've definately had hotter since then, but the sauce was fairly good in flavor and heat. The lady was staring at me when I went to pour it on the chip and when I got more than the customary 1 drop she proceeded to warn me multiple times about how hot it was, kinda gave me a chuckle.
